The invention discloses an environment art mower battery pack management system and a control method. The environment art mower battery pack management system comprises a detection module, a system controller, a motor driving module, a fault switch group, a system power supply, and a human-computer interface. According to the system controller, through the battery monomer voltage, the battery pack voltage and current obtained by the detection module, by combining with fault information fed back by the fault controller, the fault information is judged and generated according to battery state information, battery monomer voltage and the like, so that corresponding switches in the fault switch group are switched on, two motor drivers in the motor driving module are controlled, and the fault information is fed back to a battery state predictor. Meanwhile, the invention further provides a control method of the environment art mower battery pack management system. Fault judgment can be carried out on one or more battery monomers at the same time, the corresponding fault battery monomers are actively cut off, continuous power supply of the battery pack is guaranteed, and frequent replacement of the fault battery monomers is not needed.
